I'm running very similar (overlapping similar values) frequency sets for Lyme on two remotes. After about 24 hours I'm herxing. Has anyone tried this?

As long as the frequencies are not identical, this is not a problem. If they are identical, you should delay the start of the second generator for at least three minutes so you don't have the same numbers transmitting at the same time, otherwise this uncontrolled frequency duplication can cause unwanted phase problems, and even wave cancellation.

As long as you observe this caveat, doing this can be beneficial, especially for tough customers like Lyme. Some of the Spooky2 Cancer Protocols steps call for exactly this, so you will also see it in the forthcoming Morgellons & Lyme Protocol.
